Free AI UX roast

Roast my SaaS.

An AI agent signs up for your product like a brand-new user and roasts the whole first-run experience: landing page, signup, and that first empty screen where activation goes to die.

For a SaaS, the expensive UX failures aren't on the marketing page; they're in the gap between "clicked sign up" and "got value." A long form, a verification wall, an empty dashboard with no obvious first action. Each one costs activation, and average activation sits around 34%, so most signups never become users.

ClapBack walks that path as a first-time user and roasts every place it stalls: the field you don't need, the password rules hidden until you fail them, the onboarding that dumps people into a blank screen. Every finding cites the rule it breaks and ships as a Jira- or Linear-ready ticket, so it lands in your backlog instead of a Google Doc.

What the roast looks for on a SaaS

Nielsen · Visibility of system status
Landing-page clarity
Does the page say what the product does and who it's for, or is it a wall of abstract benefit-speak? Vague positioning is the first leak in the funnel.
Baymard · Form usability
The signup form
It counts your fields, checks for inline validation, and hunts for hidden password rules and forced steps. That friction turns intent into a bounce before the account even exists.
Nielsen · Recognition over recall
First-run & empty states
The moment after signup decides activation. An empty dashboard with no next action, no sample data, no path to value is where most trials go to die. The roast flags it.
Nielsen · Help users recover from errors
Error & edge states
It submits bad input on purpose to see whether your errors explain the fix or just say "invalid." Silent or cryptic failures are activation killers you never see in analytics.
Jakob's Law · Laws of UX
Pricing & trust
Confusing plans, a hidden "contact us," no clear free path. It flags the pricing-page friction that stalls buyers who were otherwise ready.
Doherty Threshold · Laws of UX
Perceived speed & feedback
Actions with no loading feedback and slow first paint read as broken. It notices the moments where a user assumes the product hung.

Questions

Will it sign up for my product?
The full roast walks your signup and onboarding as a new user, which is exactly where most SaaS UX problems hide. The free mini roast focuses on your landing page. Point it at staging if a test signup on production is a concern.
Does it export to Jira or Linear?
Yes. Every finding is written as a ticket with a severity, a screenshot, and a concrete fix, so it drops straight into your backlog without a triage meeting.
How is this different from a human UX audit?
A consultant takes weeks and a retainer and hands you a slide deck. ClapBack takes minutes and a URL and hands you tickets. It catches rule-checkable defects fast; it won't replace research into why your users behave the way they do.
Can it get past my login?
The mini roast reviews what's public. For the full roast of gated flows, you can run it against a staging environment or a demo account so it sees the product a real user sees.
